Lightning strike
Code yellow applies to Zeeland due to heavy rain and thunderstorms. The KNMI warns against lightning strikes, a lot of rain can also fall in a short time, which can cause nuisance to traffic. For Flevoland and Noord-Holland, code yellow was also issued earlier on Wednesday for heavy thunderstorms.
The rest of the country will also have to deal with thunderstorms on Wednesday, which will reduce the heat. If it does not reach 25 degrees or more in De Bilt on Wednesday, the national heat wave will have come to an end, which will have lasted a total of eight days. There may still be a regional heat wave.
